Tim -

I did this in 1993, IDL version 2. The procedure is heavily integrated
into the calling application, and would take some work to make current and
modular. If nobody else offers in a couple of days, I might just whip it
into shape or send it to you as is.

Hint: I use XOR graphics for the "rubber band" line, CURSOR to get the
endpoints in device coordinates, converted to data coords myself, and
found the coords between endpoints myself.
